Now we are looking for a Technical Support Engineer to join our team!
What You Will Be Doing:
- Providing technical support, configuration, and troubleshooting for issues with the Sumsub platform for our B2B clients.
- Performing a technical analysis of reported problems and define plans for resolving them.
- Interacting daily with other engineers to provide technical action plans or take ownership of cases that require escalation.
- Collaborating closely with other teams to answer clients’ technical questions, acting as a liaison between the client and internal Sumsub resources.
- Communicating with clients using chat, email, and outbound calls.
About You:
- Fluent in English & Mandarin (both oral and written, upper-intermediate as a minimum).
- 1+ year of experience in technical support, preferably for SaaS, web, or mobile applications. (L1 experience and a clear drive to grow into more technical work is welcome.)
- Confident with web fundamentals: HTTP requests and status codes, REST APIs, JSON, and debugging network requests in the browser's developer console.
- Able to read and write basic SQL queries to investigate data-related issues.
- Understanding of how requests flow through web and mobile SDK integrations, from the client through to the backend - enough to narrow a problem down to the right layer.
- A genuine, customer-first attitude: friendly, patient, and sincerely motivated to help.
- Analytical mindset and the ability to stay oriented in a large, constantly changing flow of information.
Would be considered a plus:
- Hands-on experience with Postman or similar tools for API troubleshooting.
- Familiarity with logging and monitoring tools (e.g. Grafana, Kibana, Datadog).
- Understanding of KYC/AML, identity verification, or fintech/compliance domains.
What We Offer:
- Remote-first, trust-based culture. Work from the place that works best for you. No mandatory office days, no attendance trackers.
- Extra time off. Your birthday is a holiday here. Add to that 10 personal days each year, seven sick days without paperwork, and extra time to enjoy Christmas and New Year.
- Work that matters. Our mission is to build a digital world that is secure, accessible and inclusive for everyone.
- Compensation. We offer fair and transparent pay, benchmarked to the market.
- Truly global. We work across continents and time zones, with teammates and customers from all over the world.
- Growth built in. Clear goals, open feedback and personal development plans.
- Team offsites. Sometimes just Slack is not enough. That is why we meet in person a few times a year.
- Getting you set up. We make sure you have access to the tools and hardware you need to do your work well.
- Friendly by design. Our logo is a dog for a reason. We keep things human, open and kind.
